I read this article the other day. There are a number of reasons why attendance is down. One huge reason is TV. The conferences and schools have sold their souls to ESPN, NBC, and others. In the case of ND, all quality opponents are night games. If you want to go to a game played in the daytime, you will get a steady diet of Navy, BC, Wake Forest or some MAC foe. The games take too long. It shouldn't take four plus hours to play a football game. The TV timeouts destroy the flow of the game.
Last night, the game started at 7:00 p.m. CST. The third quarter ended at 10:30 CST. I did not stay up to watch the fourth quarter. All of the kids in South Carolina and Louisiana, who follow Clemson and LSU, have school today. As a result of that, many of them couldn't stay up to watch the end of the game. The game ended after midnight eastern time. The selling out to TV is going to cost the game a lot in the long run.
